Puller Guns & Power Paks

Puller Guns

Puller guns are hydraulically powered units used to pull a mandrel through the workpiece. The majority of holes under 27/64" (11.0 mm) diameter in aluminum can be coldworked with the smallest gun, the WCI-300. Larger holes require bigger guns as pull force is proportional to hole size, material strength, and stackup thickness.

Restricted Access Solutions

Hand Puller

The WCIS-HP-20 is a manually operated wrench-type puller for use where access is very limited or only a few holes need to be coldworked. It can pull stackups to 2", and uses standard 300 series mandrels. A pilot is manually inserted from the rear to solidify the mandrel during coldworking. The WCI-HP-20 includes a storage box and ratcheting wrench.

Power Pak Units

All puller guns, except the WCIS-HP-20 hand puller, require a hydraulic power supply to operate. WCI offers two air powered units, the WCI-30, a small unit meant for low volume coldworking, and the WCI-10000 units, offering greater speed and intended for higher volume applications. Both units include an automatic lubrication system for mandrel lubrication.


WCIS-H10000

sleeveless-capitalThe WCIS-H10000 is a factory-oriented hydraulic power supply, able to pull a mandrel through the workpiece in less than one second. It is powered by a 2.2 HP air driven intensifier piston pump. The the H10000 produces 10,000 psi (691 Bar).

  • Does not require air-line oiler
  • Caster mounted for easy portability
  • Fail-safe systemair leak in trigger system will cause the pump to cease to function
  • Quietonly 75 dBA max
  • Air supply70 CFM @ 90 psi (1,960 L/min @ 6.22 Bar), 1/2" or larger hose
  • Dimensions13½" wide x 18½" long x 18" tall (34.3 x 47 x 45.7 cm)
  • Weight77 lbs. (35 Kg.)

WCI-30

The WCI-30 is a small, economical unit designed for applications where only a few holes need to be coldworked, such as aircraft repair shops, or where mobility is a prime requirement, such as special access situations where a larger power pak would be cumbersome.

sleeveless-capital

  • Weighs only 23 pounds for easy portability

  • Supplies up to 10,000 psi (691 Bar) hydraulic pressure
  • Requires 90 psi (6.22 Bar) clean, dry air, 1/4" ID air line
  • 1/3 HP air motor
  • Only 10" high,10" wide and 15" long (25.4 x 25.4 x 38.1 cm)

Hose Assemblies

The hose assembly connects the puller gun to the power-pak. It consists of three hoses: a high pressure hydraulic hose and two low pressure air lines. Assemblies are available in standard lengths of 10', 15', and 20', (3, 4.5 and 6 m) or other lengths by special order. All necessary fittings are included.
